The study was focused on the phosphorus migration in the soil system and the effect of phosphorus loss on the water environment through field experiments. The results showed that the runoff loss was much higher than the leakage loss;and the fertilization of P had a great effect on the loss of P in running water. Under the application rate of 102 kg•hm-2•a-1;the total P loss was 5.33 kg•hm-2;accounting for 3.59% of the total P fertilization annually. The P loss in running water was high in wheat season than in rice season and will threaten the security of water environment.
